Introduction
Considerable confusion existed regarding the type-species of Liasis. Gray (1842: 44) included childreni, amethistina, and olivacea in his description of Liasis but did not designate a type-species. Demarest In d'Orbigny, 1846, Diet. Univ. Hist. Nat. 7: 808 pp. [337], subsequently designated Boa amethistina Schneider, 1801 [= Morelia amethistina (Schneider, 1801)] as the type species.
McDowell, 1975, J. Herpetol. 9:1-79[31], apparently unaware of Demarest's designation, treated Liasis childreni [= Antaresia childreni] as the type-species, presumably based on Gray's subsequent assignment of Liasis childreni to the subgenus Liasis Gray (1849:91). McDowell also pointed out that Gray's (1842:44) concept of Liasis amethystinus was based on the same specimen that A.-M.-C. Dumeril and Bibron, 1844, Erp. Gen. 6: 609 pp. [440], later described as Liasis mackloti. Aware of these problems, Stimson and McDowell, 1986, Bull. Zool. Nomencl. 43:330-334, in accordance with Article 70(a) of the Rules of Zoological Nomenclature petitioned to have mackloti designated as the type species for Liasis. Their application resulted in Opinion 1514 (1988, Bull. ZooI. Nomencl. 45: 244) which ruled mackloti as the type-species of Liasis.
Systematic treatments of species of Liasis and for that matter most other Australian pythons over the past 25 years have added considerable nomenclatural confusion. Stimson, 1969, Das Tierreich 89: 1-49, recognized nine species of Liasis, including the three contained here, plus other species currently assigned to the genera Antaresia, Apodora, and Morelia.
McDowell (1975: 3 1- 3 3) recognized two species groups of Liasis: the olivaceus group containing olivaceus, mackloti (in which he included
fuscus), and papuanus [= Apodora papuana], and the boa group including boa [= Bothrochilus boa], albertisii [= Leiopython albertisii], and childreni [= Antaresia childreni]. Cogger, Cameron and Cogger (1983: 200-204) assigned the Australian species of Liasis and several other taxa to the genus Bothrochilus. Subsequently, Cogger, 1992, Amph. Rept. Australia. 5th ed., 775 pp.[606-·608], referred the three Australian species (plus albertisii [= Leiopython albertisii] and childreni, perthensis, and stimsoni [all species of Antaresia] to Liasis.
The current taxonomic treatment follows Kluge, 1993, Rec. Australian Mus. Suppl. 19: 1- 77, except that we prefer to recognize Liasis fuscus as distinct from Liasis
mackloti following Cogger (1992) and the arguments made by Barker and Barker, 1994, Pythons World 1: 171 pp.[30], and others summarized therein.
